Or, not really. Since my Firefox is built from source code on a 64-bit platform, all I could get while trying to install the pre-compiled extension was the following error:
“Geode” could not be installed because it is not compatible with your Minefield build type (Linux_x86_64-gcc3). Please contact the author of this item about the problem.
I have posted a comment on the Mozilla Labs’ blog post about the binary incompatibility and hope to get my hands on Geode’s source code soon for a tryout. The service sounds fun, even though it would take at least a few years for websites’ awareness of the W3C Geolocation Specification to mature enough to a point where everyday usage would be the same.
